35 ILCS 185/5-5
The General Assembly finds that certified service providers and certified automated systems simplify use and occupation tax compliance for remote retailers, which fosters higher levels of accurate tax collection and remittance and generates administrative savings and new marginal tax revenue for both State and local taxing jurisdictions. By making the services of certified service providers and certified automated systems available to remote retailers as provided in this Act, the State will substantially eliminate the burden on those remote retailers to collect and remit both State and local taxing jurisdiction use and occupation taxes. While providing a means for remote retailers to collect and remit tax on an even basis with Illinois retailers, this Act also protects existing local tax revenue streams by retaining origin sourcing for all transactions by retailers maintaining a physical presence in Illinois.
